This invention of improvements in or relating to spindles or holders for paper or other cones or tubes for machinery for w1nding yarn, thread, cord, twine and the like,

relates to spindles or holders of the kind comprising or provided with'- parts expansible vand contractible in diameter or movable outwards and inwards, away from and towards the axes or center lines of the spindles or holders for engaging and releasing paper or other cones or tubes on the spindles or holders and to devices providing parts movable outwards and inwards relatively to the axes or center lines of such spindles or holders for 1" holding and releasing paper or other cones or tubes thereon and means for operating such devices.

This invention consists in part in plates or whorls formed wholly or in part of resilient or flexible metal which presenten or by their circumferential parts edges or teeth adapted to engage with the inner sides of paper or other cones or tubes and are adapted to be changed throughout or in part from or to a flat or less bulged, dished or bent condition to or :tromv a bulged, dished or bent or more bulged, dished or bent condition and from or to a greater to or from a less diametral extension and are applied in or to spindles or holders for paper or other cones along with means by which the central parts or parts of the plates or whorls between the central parts and the circumferences may be moved or allowed to move in the direction of the axes or center lines of the plates or whorls relatively t-o the circumferential parts according to the formation of the spindles or holders and the manner in which the plates orv whorls are employed so that the plates orwhorls are enabled to engage or made to release paper or othercones or tubes on the spindles or holders.

Exemplilicatory forms of plates or whorls provided according 'to this invention are shown in the accompanying drawings in all the figures of which the same reference characters areemployed to indicate corresponding parts. Figs. l and 2 are a side elevation and diainetrical section of one plate or whorl provided according to the invention when un- 0 stressed, Fig. 3 is a side elevation and Figs. t

and 5 are diiierent diametrical sections taken respectively on the planes indicated by the lines A A and B B of Fig. 3 showing another plate or whorl provided according to the invention in the stressed condition in which it is also represented in Figs. 7 and S to be mentioned later herein. Fig. 6 is a` side view of a third form oi' a plate or whorl. Fig. 7 is a longitudinal section with some parts shown in side elevation showing one form of spindle elevation ot' the spindle or holder shown in r Fig. 9. Fig. 1l is a longitudinal section with some parts shown in side elevation showing one forni of spindle or holder furnished with two plates or whorls Jfor holding a cylindrical tube and Fig. l2 is a transverse section taken on the plane indicated by the line D D of Fig. ll. Fig. 13 is a longitudinal section with some parts shown in side elevation showing another form of spindle or holder with two plates or whorls for holding a cylindrical tube. l

Figs. l and 2 show a plate or whorl a with a iiat substantially circular central portion a and eight equal radial arms (L2 dished or bent so that the radiating arms a2 when the plate or whorl is unstressed extend to one side of the plane of the central part a in the shape of part of a frustum of a hollow cone.

Figs. 3, 4 and 5, show in the stressed and therefore dished or bent condition in which it is also shown in Figs. 7 and 8 hereinafter to loe described, a plate or whorl a differing from that shown in Figs. 1 and 2 in that the radiating arms a2* are made of two lengths, the longer a3 alternating with the shorter a4 that the plate 'or whorl when unstressed is flat and that the central hole is larger.

When the plate or whorl a shown in Figs. 3, 4 and 5 is subjected to lateral stress so that the 'lingers or arms a2* are bent from the flat CTI CII

condition to one side or face of the plate or whorl to retract the arms and lso to reduce the diametral extent of the plate or whorl a and a paper or other cone is appliedv around the plate or whorl a in contact with the ends of the longer fingers or arms a3 and the plate or whorl a is set free to return less or more completely towards the unstressed condition7 the longer arms or fingers as will become engaged with the inner surface of the paper or other cone and Abe heldtherebyfrom ret-urn-V ing completely to the unstressed condition and the stress to whichthe longer arms or fingers a3 remain subject will be transmitted to theshorter Varms or fingers so that they A will be made to bear on any surface presented to them as an abutment enabling the longer 'arms or fingers a3 to `keep the paper or other cone pulled in onedirection. n

Fig. -6 shows a whorl or plate a, in which tour 4radiating arms api* are made each -to furnish a longer and shorter radiatingjprojection aal, a4* and so present projections corresponding to the alternate longer and '7 shorter radiating arms co3, a* of `the plate or 'whorl shown in Figs. 3 and 4;. y

One illustrative embodiment of a plate `or whorl a applied according to the invention vwill be `describe(L in reference to Fi 6 and T as applied in or to a spindle or holder b with larger and smaller conical parts b, b2 at its ends for application of a paper or other conc c and mounted in a well known way of mounting cone spindles or holders in winding ma-y chines to revolve about an axis or stud el unrevoluble but pivoted or connected by a stud e to a movable arm f turnishedwith cam sur faces' f available for 'effecting the disengagement of engaging devices from cones appliedy on the spindle or holder l) in such Va way that the stud or axle (l can' be moved towards and away from a -windingdrum and turned about ,oneend or part into and out of a position vin which it is held by a detent spring, not shown, for revolution of' the holder Z) and ,winding of yarn on a cone c thereon and out of and into position for the application and removal oflcones c.. In the illustrative embodiment oi' a plate or whorl as illustrated -in Figs. 6 and 7, a `vplate a ot resilient or flexible metal of the form illust-rated yin Figs. 3 and l pnesent-ing .longer armsaf andvalternate shorter arms It* extending from va central. collar a connecting them so far as to present with the longer arms a?, azdiametral 4extent suitably greater than that of the larger end b of the spindle -or holder- ,and presenting with the shorter arms a? a diametral extent equal to or a. .little less than that-ot` the larger end of the spindle or holder Z),- is mounted loose upon a 4collar `or boss .-53 forming part of lthe spindle orv holder b and surrounding the axle or stud d so tha-tthe plate a is betweentlie largerend ofthe spindle or holder b and a sleeve or collar g loose upon thevaxle or stud d and movable lengthwise thereof by means of the cam faces f on the movable arm f. So long as the sleeve or collar g is not made to press against the plate or whorl L and their arms or lingers a are free to maintain their iull outward eXtension the plate or whorl a will remain fiat. lV hen the stud or axle (l is turned into position for a cone c to be appliedto or to be removed from the'spindle or holder the sleeve or collar f/ will be made to press against the plate a and being made -to press vit against the larger end of the part L of the spindle or holder which as usual presents a hollow 71 will press the central part intothat hollow 7L and retract the ends of the longer arms a .so as to reduce the -d-iametral-extent to .a little less than or approximate 4equality with ythat of the larger end of the part of 1the spindle or holder Y) and also ben-d the shorter arms a* in the same or nearly the samedirection as the longer arms a3. When rafter the lapplication ot a. ycone c on the spindle or holder 7) the stud or axle d is turned into :position for the revolution of the spindle yor helder 1), that v*is to say .into the position in which it is indicated in Fig. and .the 'winding `ofyar-n thereon, the plate a will be relieved of the pressure of the sleeve or collar g and vso-set free to be revolved about or relatively to the stud or axle d and the ends of its arms a3 will engage the inner side of the ycone c in position on the spindle Z) and secure the ,plate in Y.position inthev cone l0.

`Wfhen the plat-e a is pressed by means `of the collar g into the hollow L so *pressi-ng the plate a into a vdislied -or hollowed formt the ylonger arms (L3 and the shorter arms'will both hbe lpressed against the larger end of the part 1 and so be made to forni approxi-mately parts of the same frustum of a cone and afterwards when 'the plate a is relieved Voft the pressure of the collar y] and tends to return to its normalV flat Vform inthe parts formed bythe arms a, a4, the resilience of the pla/te a will cause the shorter arms a4 vto remain pressing against the larger end of the part 111 while the longer arms engaging the cone c rand tending to move further a-way from the llarger end of the part b1 will tend to pull the cone c on to the spindle or holder '7). The larger end of the part b1 is advantageously bevelled as shown to prevent 'the longer arms aof' the plate a from rocking upon it and moving their yout-er ends towards the smaller end of the spindle or holder L when the plate a is resuming or tendingr to resume its flat form.

Another illustrative embodiment oi a plate or whorl provided accord-ing to this invention will be described in reference to Figs. '9 and l() as applied lin or with a spindle or holder for paper or other cones which oomprises an axle adapted to be revolved in bearings or guides, and two conical sleeves j, Je, one larger than the other and advantageously one or both adjustable along` and secured in position upon that axle z' for example as shown in the ease of two adjustable conical Vsleeves j, la, by the one conical part le being formed with a central hole to receive the axlet' and ascrew threaded hole `furnished with a set-screw Z for securing it in position and the other being formed with a screwthreaded central hole in order to be screwed into position on a screw-threaded part z" of 'the axle z' and another screw-threaded hole furnished with a set-screw m for iixing it after it has been screwed into position. In this embodiment of a plate or whorl a so applied, a pla-te or whorl of the `form illustrated in Figs. l and 2 and presenting arms a2 extending from a central collar a connecting them and formed with a central hole so that it may be passed freely on to the screwthreaded part z" of the axle i is dished or bent so that the arms a2 extend obliquely from one face of the collar a and in the unstressed condition ofthe plate or whorl a present a diametral extent a little less than or approximately equal to that of the larger fa ce of the conical sleeve j. The plate or whorl a is placed on the axle i in position 'for the obliquely extending arms a2 to bear against the larger face of the larger conical sleeve which conveniently is bevelled as shown near the edge to receive bearing of the arms a2. A washer or collar n placed around the axle z' is provided to be pressed advantageously by means of a nut 0, advantageously a wing-nut, screwed upon the screw-threaded part i] of the axle i so that by the plate or whorl a being made flatter the outer ends of the arms a2 can be pressed into engagement with a paper or other cone or tube c applied around the conical sleeves j, In this case the plate or ,whorl a in being pressed into engagement with a paper or other cone or tube c will tend `to pull it further onto the conical sleeves y', c by the arms a2 being made to rock upon the parts of the sleeve upon which they bear.

In the application of this invention to or in spindles or holdersfor cylindrical tubes, two plates or whorls formed, applied and used generally as aforesaid are provided in or with veach spindle or holder, as 'for example in illustrative embodiments, pairs of discs or bosses corresponding to the larger ends of the larger conical parts of the spindles or holders already described as illustrative embodiments or the ends of cylinders each corresponding` to two of such discs or bosses are provided on axles or other parts to or with which plates or whorls are applied in modes generally corresponding to those hereinbefore described.

Figs. 11 and 12, showing a spindle or holder for cylindrical tubes, show a spindle or holder comprising an axis or stud cl to beturned about a stud e in a movable arm f with cam surfaces f1 mounted similarly to that shown in Fig. 7. In Figs. l1 and 1:2 a sleeve p is mounted upon the axis or stud d and adapted to be revolved around it. The sleeve y) which externally is mainly cylindrical and formed at one end with a larger lpart 221 presenting a conical surface p2 at one end is held against longitudinal movement by means ot' pegs g screwed into the larger part p1 and made to engage a groove Z1 in the stud or axis d. The sleeve p is formed internally with annular grooves and recesses r, s, t, to hinder the escape of lubricant supplied to the. surface of the axis or stud CZ by means of a longitudinal hole Z2 with radial branches formed in the axis or stud (Z. Around the sleeve y? is mounted another sleeve u capable ot' a longitudinal movement on the sleeve p. The sleeve u is ada ted to bear at one end against the conical surface p2 and at that end is provided with a collaru1 to be brought against the cam surfaces f1 in order that the sleeve u may be moved lengthwise of the sleeve p away from the conical suri'ace p2 when the axis or stud cl is turned into position for a tube to be applied to or removed from the holderl and is also provided with a collar u2 and a cylindrical part ug extending from that collar u2. A plate or whorl a similar to that shown in Figs. 3, l and 5 and to that described with reference to Figs. 7 and S is mounted around the cylindrical part u of the sleeve u and made to present one face to the collar u2. Around the sleeve u is applied a cylindrical collar e1 presenting an annular hollow w and circumferentially bevelled edge for presentation to the plate or whorl a and corresponding to those of the sleeve b shown in Figs. 7 and 8. Pegs a; screwed into the collar and made topass through slots in the sleeve u and to enter holes in the sleeve p hold the collar against longitudinal movement and turning relatively to the sleeve p and also hold the sleeve u against turning on the sleeve p. Another plate or whorl t similar to that applied around the sleeve u but with a smaller central hole is mounted around the sleeve p and made to present its dished or hollowed face to the end of the cylindrical part ua of the sleeve u and another cylindrical collar jz/ generally similar to the collar o but with a smaller central hole is secured by setscrews to the sleeve p. The collars fv, y are secured to the sleeve y? in such position that when the axis or stud d is in the position in which it is shown in Fig. ll and the arms or iingers 0,2 of the plates o1` whorls a are free to maintain their full outward extension the plates or whorls a maintain their flat form but when the axis or stud Z is turned about the axis of the stud e connecting it to the arm f the collar u1 of the sleeve u being made to bear against the cam faces f1 will be forced away from the conical surface p2 and be'made to press the plates or Whorls a into the hollows w of the collars fv, y so as to retract the arms a2 and thus to reduce the diametral extents of theV plates or Whorls a to a little less than or approximate lequality with those of the collars fu, y. Consequently as in the case of the holder or spindle shown in and described with reference to Figs. 6

vand 7, when the stud or axis d has been turned into position for the collar u1 to be acted upon by the cam faces f1 a cylindrical tube 1 of a diameter only slightly exceeding those of the collars o, g/ can be applied to them and will become held firmly upon them as the resilience of the plates a causes the arms or lingers a2 tomove outwards when the spindle or axisd is being moved back into the position in which it is shown in Fig. 10." In the movement of the axis or stud l from the position in which it is shown in Fig. 11 to the position in which the collar u1 is moved by the cam surfacesv f1 away from the conical surfaceA p2, the cylindrical tube 1 applied around the collars lv, 1/ will be released by the plates a.

Fig. 13 shows another holder for cylindrical tubes. In the holder shown in Fig. 13 an axle z' adapted to be revolved in bearings or guides is furnished with two collarsQscrewed on to screw-threads on the axle lz' and secured in Yposition upon it by set-screws 3 and provided with cylindrical circumferential parts and also with bevelled edges 2 and disposed so that the bevelled parts 2a aie directed oppositely away from one another. Two plates or whorls ct similar to those shown in Figs. land 2 but of smaller diameter and made in their unstressed condition to present the tips of their arms or fingers a2 in diametral extension a little less than or approximately equal to those ofthe collars o, y are applied around the axis or spindle i and made to present their dished or hollowed faces respectively to the bevelled parts of the two collars. Two nutsl with milled heads screwed upon the screw-threads of the axle or spindie i are provided to bear against the central collars al of the plates or whorls a so that when a cylindrical tube 1 of a diameter slightly exceeding that of the collars lv,7 1/ has been placed around them the nuts 4 being screwed inopposite directions towards one another, may be inade to press upon the collars al of the plates a and, by flattening the plates a, to press the arms a2 into engagement with the tube 1 to hold it firmly in position on the collars 2 or may be screwed in opposite directions away from one another to release the plates (L from pressure so that the resilience of the plates a may retract the arms a2 and release the tube.

In carrying this invention' into effect, plates or whorls may be formed with arms or lingers in any number leven or odd Whether such arms or fingers be of equal or unequal radialextension and whether or not the arms in the stressed or unstressed condition diverge by equal extents or angles or different extents oranfrles from the :alane or surface of reference.

It is to be understood that variations in detail may be made in carrying this invention into effect in the provision of whorls or plates and also in the construction and mounting of tlievspindles or holders in which i5 upon opposite sides thereof and atdifl'erent (Q5 distances from its center, and means foi' actuating the vmovable collar to cause the periphery of the plate to engage and release the tube.
